What project structure and templates speed up motion graphics in After Effects?

[RileyTW]

I work at a small marketing agency where I'm often tasked with creating explainer videos and social media ads, and my current motion graphics workflow in After Effects feels painfully slow and disorganized. I waste too much time searching for assets, managing messy layer structures, and redoing simple animations because I didn't set them up properly from the start. For motion designers who handle a high volume of client projects, what does your optimized project structure and pre-production process look like, from storyboarding and asset gathering to using master properties and essential graphics templates to ensure consistency and speed when revisions inevitably come in from multiple stakeholders?
